BABY-CHAIR AND PERAMBULATOR.

' To all whom t may concern.'

Y soV Be it known that I, SAMUEL P. WITHROW, a citizen of the United States, and residing atl Cincinnati, in the county of Hamilton and State Of'Ohio, have invented a new and useful Improvement in Baby- Chairs and Perambulators, yof which the following specification is a full disclosure.

"My invention relates to a baby chair, adapted tovstandupright on its base, or to `be converted into a perambulator.V

An object ofthe invention is to improvethe construction and operation of the device comprising the invention of my prior patent,v No. 700,397, of May 20, 1902.

The preferred embodiment of my present invention is illustrated inthe accompanying drawings, forming a part of this specification, in which.:-

i VFigure l is a side elevation of the. device as a perambulator. F ig. 2 is a similar view of the device as a chair. Fig. 3 is a rear elevation of the chair. Fig. 4 is a detailed section on line 4, 4, Fig. 8, with a portion broken away to showV the locking indents.

Fig.' 5 is a side elevation Vof the device as adjusted for use as a crib and showing a detachable wheel hood. Fig. 6 is a detailV rear elevation of one of the wheel hoods and -a portion of the chair body.

The chairv 1 has the seat 2, foot-rest 3 and back projections 4, enabling the chair to cured'relative to the chair back' 5, and, preferably, also, the upper portion of the chair is provided with the carrying bail 6.

To the base portion of the chair back there is secured the bearing brackets 7, 7', upon opposite sides of the chair, in which a rock vshaft S has its bearing.v -Upon the ends of said rock shaft, projecting beyond said bearing brackets, are secured the sheaves9, 9. L

To the outer face of each of said sheaves is secured a triangle frame 10, to the base portion 11 of which the wheels '12, 12 are attached. The triangle frame and wheels thusyconstitute a truck which vcanbe swung into Vposition above or below the chair vbase by reason ofthe pivotal connections established relative tothe chair by the rock shaft `and sheaves. When the truck is below the base,

- the chair becomes a perambulator, regardless Specification of Letters Patent. p

of the angle` of the chair back to `the floor, i while the dimension of the pivotal move-M ment enables the truck to be swung upwardly into approximately a vertical position along side'of the chair body.r To the? upper portion of the V,chair back is secured `bearing bracketsl, 13T-on the opposite",

sides of the chair, iny which a rock shaft14 has bearings-the ends' of theshaft projectingV outwardly beyond said brackets. On the kprojecting ends of 'said'shaft 14are secured lthe sheaves 15, 15, and to -theouter faces of' Patented 0ct.5, 1915.

Application led November 5, 1914. Serial No, 870,507. l Y

saidsheaves are secured the clamp sleeves x 16, 16, holding the inner ends of a wheeling handle 17. VThe sheaves 9 and-'l5 arecon-l nected by the belt- 18, and, preferably, the 1 nected by -a belt. As indicated at 25, the

ends of these belts are secured Yto the sheaves '$75 secured to the vupper portion of ythe chair Y Y back isa bracket 19, for supportingalock mechanism consisting 'of` rods 20, 20', alined and spaced apart-within vthe sleeve 19 vof said bracket, the inner; ends of said rods having finger grips 21, projecting through slots in'k the sleeve, the rods being forced normally apart by aspring 22 `in said sleeve.

The sheavesl, 15, aref provided with a series .of indents- 23: upon their inner faces,

ends ofv the locking rods when vthe sheaves are variouslyv adjusted.

' When Vthe device is in 4chair form, it V.may

be stood on its base or carried on the arm,

[the wheeling handle and wheel rvtruclrb'eing pact structure, withA no objectionable ',projecg tions beyond the chair body, and, if desired,

yadapted to be respectively alinedlwithftheV 'l Y the chair body maybe provided with a hous I ing or pockets for the VVupwardly folded` n wheel truck. v

To convert the chair yinto aperambulator,

the wheeling handle is unlocked "andswung l' upwardly, thereby swingingthe wheel truck downwardly below the base,lto position in which'thechair stands'on the wheels orbe'- from the floor, and any handleadjustinent, while the lchair stands on the wheel base, servesto variously adjust the' angle of the chair back to'the'floor line, without *varying* hoods 26 are made of woven cane or basket material suitably reinforced. IThe rear reinforcing strip 2? is shown as of the same length as the back projections which provides a wider licor contact (when used as a chair) thereby lessening the liabilityof upsetting.

The means for fastening the wheel hoods to the chair body consists of hooked projections '28, secured to thel upper marginal edge V.of the wheel hood and a pintle 28 secured to the forward lower edge, each adapted to engage into screw eyes 29 on the chair body. The wheel hood is held in position by a plate 30, secured to the medial rear portion ,of the hood and secured to the chair body by a thumb nut 3l. The rear of the wheel hoods are open to about one-half their height to permit the wheel trucks to swing rearwardly to operative position.

rfhe pinciple of the invention is not concerned with the number of wheels, for obviously a perainbulator,oi` a wheelbarrow nature might readily containan embodiment of this invention, and it is also apparent that other and various changes could be made in the light of this disclosure.

Having thus described my invention, l
